AIR CANADA PLANE FLEW WITH FUEL MADE FROM 50% RECYCLED COOKING OIL

The (very distant) future is here, friends. The first plane to fly using a 50/50 fix of jet fuel and recycled cooking oil. The flight has generate 40% fewer emissions than a standard flight and with people becoming more conscious of the environment, we could see a massive shift toward a greener aviation industry. Not to mention the fantastic PR a green flight could generate for a company. I know which airline I would rather choose.
